The technical field to which the invention relates

The present invention relates to a camera system, the device of choice video and method of selecting video.

The level of technology

In the camera system used in broadcast station, etc., headunit camera (GBq) to output the video signal and the control unit of the camera (BEECH) for receiving a video signal connected to each other via a three-wire coaxial cable or optical fiber cable (Japanese laid patent application No. 2005-057499 and No. 2005-064816).

Summary of the invention

When GBK is connected to BEECH via a three-wire coaxial cable or optical fiber cable one-to-one manner, the video signal is captured GBq, should in the future be extracted from a BEECH. In addition, the total signal sync GEN-LOCK, the control signal, reverse video, etc. for GBq needed for further input from the BEECH.

As a result, in the camera system used in broadcast station, etc., as many of the cables are connected to the BEECH, the necessary time and effort to connect and cable management.

In addition, when GBq, etc. are added, substituted or rearranged after one system cameras collected, you need a lot of time and effort, for example, to change cable connections BEECH.

In sist�IU cameras as described above, it is necessary to facilitate the modification of the system, etc. by reducing the number of cable connections to the BEECH.

In this respect we can consider the system with BEECH, which is the same as a lot of cameras. However, in this case, since all N BEECH must have a decoding function, it is impossible to avoid increasing the system cost. In addition, it is necessary to connect a BEECH to the video switch that operates in real time, with the help of wires corresponding to the number of cameras. However, in the video source actually used in the broadcasting, for example, when the video switch that operates in real time, mix two screens with each other, as this is enough for two input sources, which will type cable inputs corresponding to all cameras, are optional. Therefore, even in a system with BEECH, which is the same as a lot of cameras, there may be a backup piece during system configuration.

In the light of the foregoing, required to implement new and modified cameras system, device and method for selecting video, which allow you to select the desired video from multiple videos from multiple cameras and, thus, simplify the system configuration.

According to one variation�the embodiment of the invention, the camera system includes many devices cameras to output respective video signals in the form paketierung video data. A relay device is associated with multiple devices cameras to relay selected paketierung video data taken from a variety of devices cameras. A relay device includes a receiving unit for receiving paketierung video data from multiple devices cameras and a control unit to determine a selected paketierung video data from a particular one of a plurality of devices of cameras on the basis of the input control signal. Switch unit selects and outputs the selected paketservice video data on the basis of frames.

According to variants of implementation of the present invention described above, it is possible to choose the desired video from multiple videos from multiple cameras and devices to simplify the system configuration.

Hereinafter will be described preferred embodiments of the present invention with reference to the accompanying drawings. It should be noted that in this description and the attached drawings, structural elements that have substantially the same function and structure are denoted by the same reference positions, and repeated explanation of these structural elements is omitted.

(1) the Basic provisions

In the control system of the cameras, according to this variant implementation, the video signal of the camera pattiseries in the IP packet and transmitted using cable, such as Ethernet (registered trademark), over an IP network, and the receiving control unit of the camera (BEECH) receives and decodes the IP packet to output video signal. According to this variant implementation, the system has the function obtained by combining the functions of IP switching select the desired video from multiple videos from multiple cameras with select/control/effect the video camera. In the known system it is necessary to have a BUK, which is the same as a lot of cameras, so the number of interconnects between BEECH and video switch is great. In the system according to this variant implementation provides only the maximum number of BEECH necessary for the release of the video switcher. In addition, by combining the functions of management/selection and additional features the effect in the IP switch can �to habitsa functions equivalent functions video switcher, real-time, which is provided in the rear cascade BEECH, through the use of switching devices and General purpose interface Ethernet (registered trademark). In addition, simplified interconnect using IP, and easier modification of the system, including extension, etc., and integration with other IP devices.

Fig.1 shows a diagram of the configuration of the system 100 cameras according to each embodiment of the present invention. The system 100 cameras shown in Fig.1, is used, for example, in a broadcast station, etc. and includes HEADUNITS 200 cameras (GBq) and BEECH 300. GBq BEECH 200 and 300 connected to the relay device 500 using 400 cables twisted pair. Cable 400 twisted pair cable can be a cable corresponding to the standard of the Institute of electrical and electronics engineers (IEEE) 802.3, etc.

IEEE 802.3 is the standard for data transmission systems using the package pattiserie data communications in a packet with a given amount of data and liaises with the use of the package. Thus, in the system 100 cameras shown in Fig.1, GBq BEECH 200 and 300 packetizer video signal, audio signal, control signal, the total signal sync GEN-LOCK, etc. in the packet and transmit the packet via asynchronous�th transmission line. Then in the system 100 cameras shown in Fig.1, a video signal which includes video of the signal transmitted on the main line of communication, audio, signal, control signal, the total signal sync GEN-LOCK, etc. can be retrieved from the relay device 500, which is between GBq BEECH 200 and 300, or you can enter into it.

In addition, the relay device 500 outputs the video signals that have been transferred from 200 GBq, and return video signals that have been transmitted from BEECH 300. For example, these video signals can be recognized by using devices based on the monitors connected to 200 GBq, the device on the basis of the monitor (not shown) connected to the relay device 500, etc. As described above, in the system 100 cameras shown in Fig.1, a video relay system using GBK 200 can be easily configured, installed and operated at low cost.

Relay device 500 includes a configuration of a switching hub, made with numerous ports. Switching hub selects ports assignments of outputs based on assignments of packets that are injected from each port, and outputs the packets from the selected ports, respectively. Also, when the package uses the broadcast address, commuting conc�Thor maybe basically, to output the received packet from all ports.

In the known system cameras it is necessary to provide N BEECH 300, which is the same as the set of (N) 200 cameras, and all the signals from the outputs of BEECH 300 are fed to the inputs of video switch that operates in real time, rear cascade. In particular, in video format hi-vision (HD), a video codec, mainly performs the encoding process by limiting the frequency band, and each of N BEECH 300 should have a decoding function, which results in an increase in the cost of the system.

In addition, in the camera system described above, it is necessary to connect a BEECH 300 to the video switch that operates in real time and uses N cables HD-SDI (serial digital interface for transmitting video signals to high-definition formats and audio signals over a coaxial cable). However, in the video source actually used in the broadcasting, for example when the video switch that operates in real time, mix two screens with each other, as this is enough for two input sources, which will be administered, do not necessarily have N inputs. Even for the implementation of effects with the use of multisource using more complex switch enough about four screens, �and which they are played, in the known configuration backup systems exist. In this respect, when considering the minimum configuration, for example, when you select a video from the set of BEECH and broadcasting, using only commutation without effect, it is sufficient to have only one BEECH.

Thus, if there are functions corresponding to the video switch that operates in real time, or BEECH 300 with the number and implementation of the effects, not necessarily to provide N BEECH 300 with respect to N video sources. In addition, selecting the source from the camera using a video switch that operates in real time, and choose the package that use IP switching, have the same function, based on the selected source.

For this reason, this implementation option controls the functions and major parts of the video switch, operating in real time, and IP switch, thus providing the system with a simple configuration. In more detail, in this embodiment of the process performed in blocks of the video frame, as in the case video switch that operates in real time, the function equivalent to the function device for performing the process within less than the time of the video frame, fully control it using the IP of the switch, and the video frame detection�for switching the IP packet. Since such control is performed on the basis of an IP switch utility, it is possible to flexibly build the system with low cost.

In this embodiment of the function equivalent to the function of the video switch that operates in real time and used in a broadcast station, etc., can be performed for data, such as IP paketservice and transferred to video. That is, in response to an input signal for switching video switch that operates in real time, the video signal is output from the header of the next frame in the switch. Thus, when encoding and compressing the signal at IP packetization provide for the codec without frame delay, for example, a codec based on linear splitting in the standard JPEG 2000 codec based on linear splitting with low latency or codec in the elements section. In addition, the codec used to process low latency in the elements of the macroblock MPEG2 or H. 264/AVC. When using this codec be possible the processes of encoding and decoding one frame or less.

(2) Example system configuration

Hereinafter will be described first variant implementation. Fig.2 is a schematic diagram showing the configuration of a system according to the first variant implementation. The first variant of implementation, the WLAN�em basic configuration of each embodiment, which will be described below. As shown in Fig.2, the present system includes a plurality of chambers (GBq) 200 (1-N), BEECH 300, the relay device 500 and the 600 block control switching/selection. Each camera 200 is connected to the relay device 500 via an asynchronous transmission network, and a relay device 500 is connected to BEECH 300 via an asynchronous transmission network. Ethernet (registered trademark) may be an example of an asynchronous transmission network. However, the present disclosure is not limited to this.

Each camera 200 converts the video into an IP packet and outputs the IP packet. Video data may be uncompressed data or coded data and attitiude in the IP packet corresponding to the Internet Protocol. In addition, the camera 200 may paketservice reversible compressed video signal according to a method for encoding video. IP switch/video switch 500 includes section 504 of the IP switch and section 506 of the control switch selects the IP packet that needs to be entered in a BEECH 300 rear of the cascade, from the cameras 1-N (200), and outputs the IP packet in accordance with a command from the 600 block control switching/selection. Output the IP packet to re-assemble with the help of BEECH 300 and convert the signal to HD-SDI.

Unit 600 controls the switching/selection shown in Fig.2, rela�esthet control panel, video switcher, working in real time, and receives a command for selecting or switching the video camera, which outputs as a video broadcast, etc.

Fig.3 shows a detail block diagram showing the configuration of the first variant of implementation, and configuration of the relay device 500. As shown in Fig.3, the relay device 500 includes a section 500 of the analysis for the analysis of IP addresses and RTP information, section 504 of the IP switch section 506 of the switch management and section 508 of the reception/analysis/command control signal.

Section 508 acceptance/analysis/command control signal, receives a signal from the unit 600 controls the switching/selection, analyzes the received data and outputs a command for switching/selecting camera 200 in section 502 of the analysis. Section 502 of the analysis determines the transmission destination of the input from the camera 200 based on the IP header, etc. of the input data and analyzes whether the input command switching/selection. Section 502 of the analysis outputs the result of the analysis in section 506 of switch management. Section 506 of the control switch converts the result of the input of the analysis in the control signal to control section 504 of the IP switch, and outputs the control signal to the section 504 of the IP switch. In addition, the IP packet data from the spacecraft�DOI camera 200 is transmitted from section 502 of the analysis in section 504 of the IP switch. Section 504 IP switch switches or selects the input packet on the basis of a new destination that is registered in the table switching according to the control signal, which is introduced from section 506 of the management switch.

Section 504 IP switch has many ports and video signals corresponding to each GBq 200, which comes from section 500 of the analysis and which are inserted in the ports. In addition, one port is connected to output line connection BEECH 300. If IP packets are injected into the ports into which you enter video signals corresponding to each GBq 200, section 504 IP switch connects the port of destination of transmission, which coincides with the destination, registered in the switching table as a new destination to the port connected to the output line of communication and BEECH 300. Thus, section 504 of the IP switch can transmit one video from the many GBq 200 BEECH 300 on the basis of the destination registered in the switching table. In addition, section 504 IP switch selects the video signal taking into account the delay until then, while the video signal is actually switched after receiving the signal from the unit 600 controls the switching/selection and seamlessly performs video switching in units of a frame.

As described above, when the IP packet transmitting video in real time from each of� camera 200 in the relay device 500, each cell 200 that includes an encoder that encodes the video data using the encoder, pattiserie the resulting data and transmits the packet to the relay device 500.

Unit 600 controls the switching/selection accepts valid input commands to select the desired video camera 200 from the user and transmits the control signal to select the video relay device 500. Section 508 acceptance/analysis/command control signal, analyzes the control signal and sends the command in section 502 of the analysis for switching and selecting camera 200.

If the result of the analysis of the control signal is adopted, section 502 of the analysis discovers the IP address of the camera 200, required by the user and included in the analysis result, and outputs the IP address to section 506 of the control switch. Section 506 of the control switch converts the received signal into the control signal to control section 504 of the IP switch, and outputs the control signal to the section 504 of the IP switch. Section 504 IP switch commutates and selects the input packet based on the IP address that you want the user, and outputs the IP packet of the video that you want to the user in a BEECH 300 in accordance with the control signal.

In addition, when the video transmission is performed using the asynchronous transmission network, there is a difference in �artrotec transmission in accordance with the combinations GBq 200 and the repeater device 500, which leads to the difference in magnitude of the delay. For this reason, the relay device 500 transmits the reference signal from the generator 520 synchronization signal in GBq 200, and 200 GBq transmit a video signal synchronized with the reference signal, the relay device 500. Generator 520 synchronization signal can optionally be run separately from the relay device 500. Meanwhile, although the video signal is synchronized with the reference signal, since there is a difference in the transmission paths in accordance with the combinations GBq 200 and the repeater device 500, it is assumed that there is a difference in the values of the delay 200 GBq. For this reason, the delay between GBq 200 and the repeater device 500 receives with section 502 of the analysis. Section 502 of the analysis adjusts the delay values for decision making regarding the optimal value of the delay. About possible delay notify GBq 200, and 200 GBq respectively sets the video buffers for adjusting the separate synchronization of the video signal which is sent to the relay device 500. As a concrete way for the adoption of a resolution relating to the delay, there is a way to adjust the video buffer to resolve the delay GBq 200 with the largest delay, which is equal to the value of� delays other 200 GBq. In addition, the installation of the video buffer can be performed by using the relay device 500. Allowing the delay values to be equal to each other, it is possible to reliably prevent video distortion when switching video.

If the IP packet is adopted from section 504 IP of the switch relay device 500, BEECH 300 decodes the IP packet, and outputs the decoded packet as a video signal HD-SDI, etc.

When switching the video camera 200, the section 504 IP switch identifies the video frame and switches the IP packet including header data forming a video frame. Hereinafter will be described a method for identification of the video frame.

Fig.4 shows a diagram showing the configuration of the header in the format of the transport Protocol real-time (RTP), which is used when transmitting data obtained by encoding video. Usually determine the information in the header, despite the coding scheme, which will be retained. Fig.5 shows a diagram showing the information about the parameters of the RTP format (Fig.4). In order to identify the video frame, use the token bit that has the abbreviation "M" in Fig.5. Usually, as bits "M" of the marker shown in Fig.5, set "1" in the packet comprises destination data of the video frame. Thus, when the bit marker "M" detected by double�and 504 IP switch is set to "0", the packet with the same IP address is the title of the next video frame. In addition, when "M" is set to "1", it is possible to identify that the packet with the same IP address ends.

(3) the procedure for the switch management

Fig.6 shows the algorithm showing the sequence of operations of the control switch, in which section 504 IP switch performs video switching. First, in step S10, the signal switching/selection corresponding to the user input, receive from the 600 block control switching/selection. After receiving the signal switching/selection in step S12, register new destination (IP address) in the table switching section 504 of the IP switch. However, before you actually perform the switching control on the basis of the switch (as long as there is a step S20), the IP packet will not be commuting in a new assignment. In step S14 analyze the header and analyze the RTP header of the RTP packet in the payload data area of an IP packet having the IP address corresponding to the user input.

In step S16 determines whether the token bit "M" of the RTP packet header is set to "1". If the bit marker "M" is set to "1", the step S18 to perform in order to perform inference analyze the IP packet in the current assignment. Then perform step S20 to perform UE�providing switched based on the switch and change the switching table based on the new assignment. Thus, the next IP packet commute on the pack with a new appointment. Meanwhile, if the bit marker "M" has the value "1" in step S16, then perform step S22 to perform the analysis of the RTP header for the next IP packet in the same manner as in step S14. By using the above-described control can perform switching from the header of the next frame.

Fig.7 shows a diagram for explaining switching of the signal in the control (Fig.6). It is assumed that there are video frames #1, #2 and #3, and each video frame pattiseries in the IP packet and is entered in a relay device 500.

Fig.7 is illustrated on the basis of the system with the number GBq N and the number N of BEECH. The switching table is represented by N inputs from GBK and corresponding N outputs in BEECH, as shown in table 1 below. Fig.7 shows an example of a switching destination port by changing the destination address, but the implementation is not limited to this example. The source address in the switching table can be changed so that it was possible to switch the source port, as shown below in tables 1 and 3. The destination address in the switching table can also be changed so that it was possible to switch the source port, as shown below in tables 1 and 2. (In this latter embodiment, the destination address signals SAM and SAM you can modify Thu�you could switch the ports sources SAM and SAM, because this table only shows the relationship between input and output. Thus, modifying the destination address in the table is equivalent to changing a corresponding address of the source, which means the switching of the source port.) These two additional options for implementation applicable to a system having a number N GBq and 1 BEECH, as shown below in Fig.2 and table 4.

As described above, if the signal switching/selecting accept in step S10, then the new assignment is recorded in the table switching section 504 of the IP switch. As shown in Fig.7, the change in the new appointment performed (step S20) after the discovery of bits "M" of the marker and switching the routing table of the switch. In the period of time when the commute table, the IP packet is output to the new port of destination. With this control you can perform the commutation process in blocks of the video frame, which equivalen�Yong video frame of known video switch working in real time and use the IP of the switch.

Meanwhile, Fig.8 shows the case where the decoding process is performed in blocks of the video frame. When the decoding process is performed in blocks of the video frame, since the decoding process is performed after buffering all the pieces of data of video frame 1, we need a predefined time until and unless you receive the data frame 1 at the end after the reception of a control signal for switching video and additionally not decode'm buffering and frame 1. For this reason, as shown in Fig.8, when the signal switching/selection was adopted in the middle of the video frame #1 after the expiry of the specified period of time required for receiving data of the video frame #1 at the end and additional decoding of the data frame #1 can be shown on the next sync timing frame for the first time. Meanwhile, Fig.7, after changing the destination, you can display the video when switching from the video frame #2. For this reason, in the case of Fig.8, an important delay may occur when video switching as compared to the case of Fig.7. In the present version of the implementation, as the processes of encoding and decoding performed in the elements of the blocks of multiple lines, as shown in Fig.4, after receiving the control signal for switching the video you can directly switch the video from the next frame.

In addition, in the system of the present embodiment, the unit 600 controls the switching/selection can be performed with the possibility of a decision in relation to the video channel, which will be commuting/select using a relay device 500 (IP-switch) with the maximum number of video that is required for synchronous output. Thus, you can control the video by performing the decoding process using only the necessary BEECH 300.

In addition, in the present variant implementation, the selection of the video frame is shown as an example. However, the audio data can be selected. For example, in the case of a system that reproduces audio, synchronized in units of a frame of the video frame, the relay device 500 may detect the packet including the header of the audio frame, similar video, and switching the IP packet using the limiter audio frame.

According to the first variant implementation, as described above, if there are functions corresponding to the video switch that operates in real time, or BEECH with the amount necessary for an effective process, there is no need to include N BEECH on the sources of the N cameras. In addition, since the function of selecting the source from the camera using a video switch that operates in real time, ek�ivalentine the package using an IP-switch, on the basis of source selection, functions and basic parts of a video switch that operates in real time, and IP switches are fully manageable, thus completing the build system with a simple configuration. Hence, according to the present embodiment of the video frame is detected for switching the IP packet to ensure that you can fully control the function that is equivalent to the function device for performing the process in blocks of the video frame and within less than the time period of the video frame, as in the case with a video switch that operates in real time and using an IP switch. Since such control is performed on the basis of an IP switch utility, has the flexibility to build the system with low cost.

For example, the minimum number of sources you can enter in the input video switch that operates in real time, and the number of BEECH 300 can be reduced, thereby obtaining a system with a simple configuration in which the number of interconnects is small. Therefore, the relay device 500 can have a switching function in order to obtain a simple configuration in contrast to the known system of cameras, which is necessary to provide N BEECH, which is the same as mn�the number N of cameras and all outputs are entered in BEECH video switch that operates in real-time back stage.

You can also switch the packet, which is transmitted using the Ethernet (registered trademark), using the General-purpose switch, thus completing the construction of a system with a low cost and with high similarity to the PC, etc., which simplifies the modification of the system, including the extensions, etc. and integration with other IP devices. For example, the synchronization signal, the management team, sound, receipts, Taree (tary) video, reverse video, etc. in the camera multiplexers in the same cable through the IP packet to achieve a simple configuration.

2. The second variant of implementation

(1) Example of system configuration

Next will be described a second variant implementation of the present invention. Fig.9 shows a diagram showing the configuration of a system according to the second embodiment of the. The second variant of implementation can be applied to the case where the visual effect, such as fade or the gradual disappearance of an image occurs when switching video. In the first variant of implementation, BEECH 300 performs the process in the rear cascade relay device 500. However, the second variant implementation uses the system obtained by �of obyedinenie BEECH 300 with repeater device 500 (an IP switch/switch). Thus, as the output signal relay device 500 video output HD-SDI, etc.

Fig.10 shows a diagram showing the configuration of relay device 500 according to the second variant implementation. As shown in Fig.10, the configuration of the second embodiment additionally includes BEECH 302 and 304, section 510 of video effects switcher and section 512 of coding/IP packetization in addition to the configuration of the relay device 500, according to the first variant implementation. In addition, the second variant implementation includes a block 602 control switching/selection/effects instead of the 600 block control switching/selection according to the first variant implementation.

Managing the switch by using the section 504 IP switch performs the same way as in the first embodiment of implementation. In the second variant of implementation, the video signals with two appointments before and after video switching is introduced in BEECH 302 and 304 BEECH, respectively. Then the output data is decoded using BEECH 302 and 304 BEECH, treated effects in section 510 of video effects switcher.

Section 510 of the video effect of the switch has the function of effect, such as erasing/blending, and executes a process based on the commands from the block 602 control switching/selection/effective�AMI. When the user wishes to perform an effect with video switching, the user enters the request in block 602, the control switching/selection/effects. For example, when performing erasing/blending in respect of the release of the video And BEECH 302 and output video from BEECH 304 section 510 of video effects switcher performs a synthesis process video And video B on the basis of user input, which introduces in block 602, the control switching/selection/effects. Since the processed video is displayed on the monitor provided in the camera 200 (1-N) as a reverse signal, the video undergoes a process of coding and process IP packetization in section 512 encode/IP packetization and presented in section 504 of the IP switch. The processed video is returned from the section 504 IP switch in 200 GBq (1-N) through section 502 of the analysis and displayed on the monitors provided for each 200 GBq.

As described above, in the present variant implementation, the feedback signal is output to 200 GBq (1-N) through section 504 of the IP switch to the function equivalent to the function of the multi-BEECH, you can perform via IP transmission. Thus, operators 200 GBq (1-N) can see the video of choice currently on the monitors provided in the camera 200, and the effects of video switching.

According to a second embodiment of the as described above, pretranslational 500 can have a function of processing effects for in order to simultaneously perform the switchover process and performance effects in relation to the video.

3. The third variant of implementation

(1) Example of system configuration

Next will be described a third embodiment of the present invention. Fig.11 shows a diagram showing the configuration of relay device 500 according to a third embodiment of the. In the configuration shown in Fig.11, the monitor 700 is connected to the relay device 500 is different than the configuration shown in Fig.9.
